Windows 10: Speed up USB3 File Transfer

I was copying some large Hyper-V vhds to an external ssd from an internal ssd via usb3, and I was getting a sedate 130 MBS even through the ssds can handle close to 500 MB/S and USB3 can handle up to 480 MB/s.

Of course, we all know that in the real world, you are lucky if you get 50% of that - so 240 MB/s is a reasonable target.

After googling, I found a truly simple change that sped my transfer up by 50% to 200 MB/s.

I simply changed the SDD write cache properties as below from device manager.

Only minor downside is you must eject the drive to safely remove it (should do this anyway).

USB3 device disconnecting when transferring files.

Hello!

I've recently built a new PC and everything is working fine, well almost everything. There are 4 USB ports on the case front panel. Two of them are USB2 and the other two are USB3. My problem lies with the
USB3 ports. Neither of them work when using a USB3 capable stick. File transfers fail within seconds, then you hear the usb stick disconnecting and reconnecting.

I can use a USB2 stick in both of the troublesome ports and files copy perfectly fine (at 20mb/s). The USB3 sticks work perfectly fine on on the USB2 ports and even the USB3 port directly on the motherboard
(at ~57mb/s). The problem occurs only on the front panel USB3 ports when copying at USB3 speeds (~57mb/s).

So far I have tried:

• Updating BIOS
• Updating USB drivers
• Updating Windows 10 to latest version
• Disabling power saving for USB devices in device manager
• Remove and reconnect USB3 cable on motherboard
• Verify if the issue is not the HDD that I am copying from

The motherboard and case in question are:

• Gigabyte Z370 HD3P
• NZXT Source 340 Elite

I am looking for any help or tips regarding this issue as my google skills are failing me.

 

Slow data transfer speed.

Hi,

One of the possible reason that this issue occurs is due to the driver compatibility after Windows upgrade. For us to isolate the issue, we’ll need the following details:

• What type of data transfer speed are you referring to? Is it internet connection speed or file transfer speed?
• If you are referring to file transfer speed, are you using USB drive or Bluetooth to process file transfer? or,
• If you are referring to internet connection speed, are you using Ethernet cable or Wi-Fi?
• Can you tell us any troubleshooting you've done so far?

We'll be waiting for your response.

You write "the file transfer speed drops to zero", yet the xcopy command does not provide you with any feedback about speed or progress. I suggest you do this to drill down a bit further:

• Examine the event logger (as mentioned before)
• Use robocopy instead of xcopy:
  
  robocopy F:\ D:\ /s
• Repeat the copy process on a different machine
